SUPPLY-CAN FOR CREAM-SEPARATORS.

Specification of Letters Patent. Patented May 26, 1914.

Application filed March 13, 1909. Serial No. 483,115.

To all whom it may concern Be it known that we, WILBUR W. MARSH and CHARLES H. HAoKE'r'r, citizens of the United States, residing at lVaterloo, in the county of Blackhawk and State of Iowa, have invented certain new and useful Improvements in Supply-Cans for Cream-Separators, of which the following is a full, clear, and exact specification.

The invention relates to centrifugal cream separators, but more particularly to the supply can or reservoir adapted to contain the milk, and from which it is fed to the bowl to be separated.

The primary object of the invention is to secure an improved supply can for centrifugal separators that is simple and economical in construction and eflicient in operation.

A further object is to provide in a supply can of the class described an improved faucet for feeding the milk to the separator bowl.

A further object is to provide in a supply can of the class described improved means for preventing the faucet from being torn loose from the can when the can is allowed to rest on flat surfaces, as on a table top, or on a floor.

A further object is to provide in a supply can of the class described an improved bottom adapted to readily drain the can and serve to protect the bottom against rust.

To the attainment of these ends and the accomplishment of certain other and useful objects which will appear, the invention consists in the features of novelty shown in the drawing forming a part of this specification, and as hereinafter described in said specification and more specifically pointed out in the appended claims.

In the said drawing, Figure 1 is a view in vertical section of the supply can taken through both can and faucet on line 11 of Fig. 2. Fig. 2 is a plan view with a portion of the can rim broken away to show the manner of attachment to the separator.

The principles of the invention may be applied to a supply can of any desired form, either rectangular or-cylindrical in form, as illustrated in the present embodiment, which is the preferred form, and in which the side walls are indicated by the reference character 10 in the drawing.

11 is the bottom preferably formed integral with the sides so that both sides and bottom are spun from an integral sheet of metal, thus dispensing with the necessity for soldered joints. A circular central portion of the bottom as indicated at 11 is formed upwardly a little beyond the plane of the peripheral portion of the bottom. This'construction serves to cause the bottom to be thoroughly drained since the peripheral portion is lower than the central portion, and the outlet for the faucet is formed-in this peripheral portion and consists of the elongated slot 12 extending from the outer edge of the bottom toward the center almost the entire width of the depressed peripheral portion. This slot 12 is also continued upwardly a short distance in the side wall 10 of the can as shown more clearly in Fig. 1 of the drawing, thus affording a clear passage way or opening into the faucet 13 which has the barrel thereof formed with a gullet or extension 13- secured on the underside of the bottom of the can immediately surrounding the slot 12, thus increasing the size of the intake to the faucet and securing a more rapid and unifo-rmfiow of liquid into and through the faucet. The barrel of the faucet terminates at itsouter extremity with the usual downwardly extending branch 13 provided with the closure member let. On the under side of the barrel of the faucet a downwardly projecting member 13, preferably formed integrally therewith is provided. This member extends slightly below the plane of the discharge end 13 of the faucet and the side of the can bottom opposite the faucet and is adapted to furnish a foot or support to shield the discharge end 13 of the faucet, which, as it projects downwardly ordinarily contacts with any flat surface on which the can may be set and the leverage due to the distance of the discharge end from the point of attachment to the can frequently results in injury to the walls of the can or in loosening the faucet from its attachment to the can. In order that the support 13 be most eflicient, it should be located on or within the periphery of the can bottom, but

it is preferred that it be located immediately 7 under the outer edge of the bottom, as shown in Fig. 1.

The sides 10 of the can are preferably formed approximately at right angles to the bottom for a short distance from the bottom as indicated at 10, thus affording a convenient shape for its support on the spider 15, the outer ends of the arms of which are extended upwardly adjacent the sides 10*,

and at least one of the arms provided with a suitable tightening thumb screw 16 threaded therein for securing the can in position on the spider. As a protection to the walls of the vessel at the points of contact with the upwardly extending portions of the arms of the spider, the reinforcing members 17 of suitable sheet metal are soldered to the sides 10% Above the lower portion 10 the sides of the can are formed bulging or protuberant, preferably being of greatest diameter about midway between the bottom and the top thereof. Around the upper edge of the walls 10 the material is drawn outwardly to form the relatively wide flange 18 for strengthening purposes, and to provide convenient means for the hands of the operator in lifting the can, thus dispensing with the usual riveted or otherwise attached handles which frequently become loosened and injure the walls of the can.

The bulging or protuberant shape given to the sides of the can serves the purposes of increasing its capacity without a corresponding increase in appearance, and also prevents splashing of the milk in filling, since the fluid forced upwardly by the agitation of pouring into or filling the can, will also be deflected inwardly and caused to fall within the walls of the can.

In order that the invention might be fully understood the details of the preferred embodiment thereof have been thus specifically described, and it will be understood that many changes in details of construction may be made by those skilled in the art without departing from the purpose and spirit of the invention.

What we claim is:

1. In a supply can for centrifugal separators, in combination, side walls and a bottom formed integrally therewith, there being an elongated discharge opening in the said bottom, a faucet secured to the bottom adjacent the said discharge opening and communicating therewith, a clownwardly discharging nozzle at the outer extremity of the faucet extending downwardly from the body of the faucet, and a leg on the faucet between the nozzle and the end of the faucet attached to the can bottom whereby when the can is set upon a plane surface the nozzle of the faucet will be kept from contact with the plane surface by the leg.

2. A supply can for centrifugal separators comprising in combination side walls and a bottom, the said bottom being provided with a discharge opening, a faucet provided with a downwardly discharging nozzle and a closure member or gullet, said faucet being secured to the exterior of the can bottom adjacent the opening therein and communicating therewith to form a discharge passage leading from the can, and a leg secured to the faucet between the nozzle and the end of the faucet attached to the can bottom, whereby when the can is set upon a plane surface the nozzle of the faucet will be kept from contact with the plane surface by the leg.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, on this 10th day of March A. D. 1909.
